IMPRovnD 'cVHANnnLuNG-Toon."

The Schedule referred to4 in these Letters Patentand making-part of the-eume.

Be it known that I, Gunners D.EDMANDs, of Sau# y Agus, in the county of Essex, and State of Massachusetts,

` have invented a new and useful Improvement in Ghanhelling-Tools; and I do hereby declare that the following-is a full, clean-'aud' exact description ofthe construction and operation of"` the same, reference. beinghad to the accompanying drawing, forming a part of thisspecification.

3 This invention is of a 'new channelling-tool for making, in the soles of boots and shoes, a channel for laying the stitches or' pegs in.

rEhis channel requires, when closed, to. resemble, in cross-section, thats'howu in Figure 10, 'in which z is -the' circular channel in the leather, and y, the slit going down to it.

A tool, to,makethisiusasatisfactory manner, must operate on the leather, as shown in Figure 11, scooping out the p'ath z, and vin openingy slit y, spreading the sides and rolling them over on the sole, as a share and mould-board Aturn turf.

To do this requires a` tool of peculiar construction. For convenience sake, it is'made in two parts.

Figs. 1 to 4 represent the knife- Figure lbein'g a frnty elevation; Figure 2, a side view, the front of theknife down; Figure 3, -a'perspective; and

Figure 4, a bottom plan. Figs. 5 to 8 represent the scoop, or channel-former, which gonges the bottom of the chanuel- Figure 5 being a front elevation; Y Figure 6, a side view', the rear end upward; Figure 7, a back view; and Figure 8, a bottom' plan.

Figure 9 is a front elevation of' the combined tool,

arranged for work.

'lhe slitting-knife has a triangular shape, ,with a broad back, and bevelled end, as shown -at A, the body of the knife-block being pierced 'with hole B, to fasten the two parts of the tool together.

The sides of the knife-blade, or slitter, are formed exactly coincident withthe median li'ne of the blade, but is a littleto one side of it, and the knife is adjusted, as shown in iig. 9,' so yas partly to cover hole D ofthe Ach:tunel-gouge. o.

This gouge is pierced with hole D, not exactly on the median line, but somewhat on one side; and in work, the larger side is placed nearest the edge of the sole, thuspreventing the knife from drawing out.

' That the tool may draw down into the bottom of the channel, the gouge is bevelled to the rear, as shown in iig. 6, so that its cutting-edge inclines downward, and

the sides: are formed with.- holIowlines,-that the narf vagainst it as the tool moves through it. 'The forward edges of hole D are sharpened, as is also the edge of knife A. i

In operation, this tool being screwed together, as shown in iig. 9, by pin through holes B and edge-of knife A cuts and spreads a slit in theleather, and the gouge draws down into the leather, enttiug with its lower edge yand sides, and rolling, bymeans of its formed sidesthe leather upward and outward, as shown in iig. 11.

Iclaim as my inventionl. The formation of slitting-knife A, with its edge on one side of the median line of its body, and its blade with a broad back to completely cover the Upper part of hole D, when arranged in connection with the gougeknife, having its lower end bevelled upwardv and backward, as and for the purpose described.

2. The adjustment of the gouge, with its hole D not in the median line of the tool, but removed toward the interior side of the channel it is to out, when said gouge has its sides hollowed and curved upward, outward, and backward, as and for the purpose described.
